1. 16. Towards Sustainable Construction: Life Cycle Assessment of Railway Bridges

   Författare :Guangli Du; Raid Karoumi; Håkan Sundquist; Helge Brattebo; KTH; []
   Nyckelord :Life cycle assessment; LCA; Environment; Railway Bridge; Sustainability; Järnvägsgruppen - Infrastruktur; Järnvägsgruppen - Infrastruktur;

   Sammanfattning : Since last few decades, the increased pressure from the environmental issues of natural resource depletion, global warming and air pollution have posed a great challenge worldwide. Among all the industrial fields, bridge infrastructures and their belonged construction sector contribute to a wide range of energy and raw materials consumptions, which is responsible for the most significant pollutions.

3. 17. Towards Model-Based Development of Self-Managing Automotive Systems : Modeling, Simulation, Model Transformations and Algorithms: Supporting the Development of the DySCAS Middleware

   Författare :Tahir Naseer Qureshi; Martin Törngren; DeJiu Chen; Ivica Crnkovic; KTH; []
   Nyckelord :Dynamic Reconfiguration; DySCAS; Self-Managing Systems; Load Balancing; Quality of Service QoS ; Model-Based Development; Modeling; Simulation; Model Transformation; Middleware; Embedded Systems; Component Based Design; Unified Modeling Language UML™ ; Discrete Event Systems; Real-Time Systems; Software Architecture; Simulink®; SimEvents™; Distributed Systems.;

   Sammanfattning : With the increased usage of electronics, embedded computer systems, software and networks in modern vehicles, the complexity is also increasing in terms of the development process, functionalities as well as their implementation. On one hand there is a need for efficient and systematic development, and on the other hand the systems are required to have enhanced post-deployment time configuration management support. LÄS MER

4. 18. System Expansion and Allocation in Life Cycle Assessment With Implications for Wastepaper Management

   Författare :Tomas Ekvall; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modelling; paper recycling; waste incineration; environmental life cycle assessment; LCI methodology; allocation; waste management; system expansion; system boundaries; life cycle inventory analysis;

   Sammanfattning : The choice of system boundaries and allocation methods can have decisive effects on the results and conclusions of a life cycle assessment (LCA). System expansion makes it possible to model the indirect effects of a decision; however, this modelling is often based on inaccurate assumptions. LÄS MER

5. 19. A Model and Implementation of a Security plug-in for the Software Life Cycle

   Författare :Shanai Ardi; Nahid Shahmehri; Nathalie Weiler; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Software security; Vulnerability modeling; Plug-in; Software development process; Software life cycle; Computer science; Datavetenskap;

   Sammanfattning : Currently, security is frequently considered late in software life cycle. It is often bolted on late in development, or even during deployment or maintenance, through activities such as add-on security software and penetration-and-patch maintenance. LÄS MER

7. 20. Ride The Wind : Symbiotic Business Model Innovation for the Chinese Wind Power Industry

   Författare :Lihua Liu; Mike Danilovic; Maya Hoveskog; Susan Lijiang Sun; Bingwen Yan; Högskolan i Halmstad; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Symbiotic Business Model; Business Model Innovation; Wind Power Innovation; China; Goldwind; 共生的商业模式，商业模式创新，中国，风电行业创新，金风科技;

   Sammanfattning : China has become one of the world’s leading countries in renewable energy, particularly in wind power. Goldwind Science and Technology has become not only the largest wind turbine manufacturer in China, but also one of the largest in the world. LÄS MER
